Well I ordered it and its on the way from England. This stuff is apparently big in England and Germany. It is on EBay ,but only from England and Germany. Fixing that rust on those new Mercedes!!This is the stuff I used in the pen I was looking for.
It turns the rust into an inert 'metal', it stops rust, it doesnt 'encapsulate' it, and then new rust 'grows' next to it. It chemically changes it to a black type metal I cant spell,....sorry. Then put a few coats of touch up paint on it, then clear coats layers, and its fixed. I know it works on surface rust and tiny nicks, dont know about rust rot. But I have never had a car with rust rot on it. I will post pics as I fix these spots and show how well it works. The brush in this 30ML bottle, just like touch up paint, looks like it will be easier maybe than the pen type I had before.
